I have codes c1020 left rear wheel speed sensor cir unit, c102b right wheel speed sensor circuit, c1035 right rear wheel speed comparative performance, c1032 right wheel speed sensor signal erratic performance, c102a left rear wheel speed comparative performance. All at the same time. These codes come on after I changed the rear right axel bearing. The plug on the abs senso4 broke so i replaced it.. Help please.

Sounds like the bearing may not have been seated on the axle properly IMO. That explains misalignment for the sensor and the difficulty to rotate. Who did the work putting the bearing on the axle? Did they use heat or a press to install?

I pressed it, i added my code problems to this thread. I just took the axel back off and pressed it again to make sure it was seated all the way. Should I replace the bearings and races again and see if that fixes it

The issue is more likely a sensor/ connector issue. I'd look at clearing codes and swapping the L and R sensors if you're certain the wiring isn't damaged. The tone rings should be free from debris so they're picking up the right count.
